AKG Acoustics C 451 B manual Description

2 Description

The C 451B is an updated rerun of a classic AKG condenser mi- 2.5 Summary crophone, the C 451 EB + CK 1. The new C 451B, however,

uses a fixed capsule to eliminate the mechanical problems of the original modular design. The microphone is the perfect choice for any application where sounds, particularly their tran- sient content, need to be captured with maximum accuracy.

Owing to its extremely light diaphragm, the microphone is highly insensitive to handling noise. An all-metal body provides efficient protection from RF interference and the microphone is rugged enough to give excellent results even under very harsh conditions.

A switchable 10-dB/20-dB preattenuation pad increases the microphone's SPL capability when close-miking high-energy sound sources or driving preamps or mixers with limited head- room.

A switchable highpass filter at 75 Hz or 150 Hz helps minimize low-end distortion that may be caused, e.g., by rumble or wind noise. The slope of the filter is approx. 12 dB/octave and its cor- ner frequency (3 dB down point) is selectable at 75 Hz or 150 Hz.
